Simple effective gps

After trying and returned a garmin 3597, very disappointed despite tested and opinion, it does not mean anything, at least for the experience I had in (weak voice, loss of satellites in cities, update long and tedious, complicated brief for what he is asked to do ...), the TOMTOM 1005 is really effective, good guidance for motorway exits, an audible voice with street names, traffic impeccable hd no need to plug a smartphone like the garmin and no loss of satllites in town, sufficient brightness, very readable card, although reported danger zone
